Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The interventions included postural re-education (arm 1), progressive resisted back extension exercise (arm 2), both (arm 3) and control (arm 4).
The intervention period lasted for 12 weeks
Arm 1 - Postural assessment and treatment by a physiotherapist including a home exercise programme. Three 20 - 30 minute sessions over the 12 week period.
Arm 2 - Gym based strengthening programme with one initial instruction and two review sessions by the researcher lasting 20 - 30 minutes. The participants were asked to do their exercise programme of 4 sets of 10 repetitions, 3 times a week for 12 weeks. Each session took approximately 15 minutes.
Arm 3 - Attended the gym and received postural re-education from a physiotherapist as above.
Arm 4 - Received no treatment intervention and were instructed to continue their normal daily routine.
Both normal and stroke groups were randomised to the four intervention groups.

Summary
Brief summary
The aim of this study is to determine whether thoracic kyphosis (stooped posture)can be reduced using two commonly used treatment modalities. The first, postural re-education, was found in a recent survey to be the most commonly used treatment modality amongst Australian Physiotherapists. The second, progressive resisted strengthening is supported by level 1 evidence in terms of strengthening but not reduction of kyphosis. The study involves the assessment of these strategies seperately, together and not at all in both a stroke and a non stroke poulation.
